Insect Ecology: An Ecosystem Approach, Fourth Edition, follows a hierarchical organization that begins with relatively easy-to-understand chapters on adaptive responses of insect populations to various environmental changes, disturbances, and anthropogenic activities, how insects find food and habitat resources, and how insects allocate available energy and nutrients. Chapters build on fundamental information to show how insect populations respond to changing environmental conditions, including spatial and temporal distribution of food and habitat. The next section integrates populations of interacting species within communities and how these interactions determine structure of communities over time and space. Other works in insect ecology stop there, essentially limiting presentation of insect ecology to evolutionary responses of insects to their environment, including the activities of other species. The unique aspect of this book is its four chapters on ecosystem structure and function, and how herbivores, pollinators, seed predators, and detritivores drive ecosystem dynamics and contribute to ecosystem stability. Provides the most advanced synthesis of insect ecology, with updated material throughout and new chapters Presents the roles of insects in delivery of ecosystem services and applications to pest management and conservation Features full coverage of ecosystem structure and function balanced with essential background on evolutionary aspects Includes case studies highlighting practical and theoretical applications for topics covered in each chapter

Dieses Ökologie-Lehrbuch führt in leicht verständlicher Weise in die Grundlagen – von den theoretischen Fundamenten bis zu Ihren praktischen Anwendungen - ein. Durchgehend farbige Abbildungen, einfache didaktische Elemente und eine Fülle an Beispielen machen dieses Buch zu einem idealen Einstieg in die Ökologie für Studierende aller Studienabschnitte. Neu in der 3. Auflage sind zusätzliche Erläuterungen in Form von Sprechblasen in den Abbildungen und die neue Gliederung des Textes in 5 Abschnitte. Ökosystem und Biogeochemie werden ausführlicher behandelt und hunderte neuer Studien sowohl für die grundlegenden als auch für die angewandten Aspekte der Ökologie werden einbezogen.

Der stumme Frühling erschien erstmals 1962. Der Titel bezieht sich auf das eingangs erzählte Märchen von der blühenden Stadt, in der sich eine seltsame, schleichende Seuche ausbreitet … Das spannend geschriebene Sachbuch wirkte bei seinem Erscheinen wie ein Alarmsignal und avancierte rasch zur Bibel der damals entstehendenÖkologie-Bewegung. ZumerstenMal wurde hier in eindringlichem Appell die Fragwürdigkeit des chemischen Pflanzenschutzes dargelegt. An einer Fülle von Tatsachen machte Rachel Carson seine schädlichen Auswirkungen auf die Natur und die Menschen deutlich. Ihre Warnungen haben seither nichts von ihrer Aktualität verloren.

With few exceptions, insects are perceived in industrialized countries as undesirable pests. In reality, relatively few insects interfere with us or our resources. Most have benign or positive effects on ecosystem services, and many represent useful resources in non-industrialized countries. Challenging traditional perceptions of the value of insects, Insects and Sustainability of Ecosystem Services explores the ways insects affect the ecosystem services we depend upon. It also fosters an appreciation for the amazing diversity, adaptive ability, and natural roles of insects. The book discusses how the ways in which we manage insects will determine an ecosystem’s capacity to continue to supply services. It reviews aspects of insect physiology, behavior, and ecology that affect their interactions with other ecosystem components and ecosystem services, emphasizing critical effects of insects on the sustainability of ecosystem processes and services. The author examines the integration of insect ecology with self-regulatory aspects of ecosystems that control primary production, energy and nutrient fluxes, and global climate—functions that underlie the sustainability of ecosystem services. Clearly, we need environmental policies that meet needs for pest control where warranted, but do not undermine the important contributions of insects to sustaining ecosystem processes and services. With in-depth coverage of the multiple, often compensatory, effects of insects on various resources or ecosystem services and on the consequences of control tactics for those resources or services, Insects and Sustainability of Ecosystem Services recommends changes in perspectives and policies regarding insects that will contribute to sustainability of ecosystem services.
